流程的擬定我国某地的钴土矿含氧化钴(CoO)达2～3％左右,含钛氧(TiO_2)达2％左右,含MrO_2在20％以上,其他如镍与铜亦含有千分之几。我们处理此种钴土矿,应尽可能地综合提取所有这些有价金属,尤其是除钴而外,特别应着重于钛、锰、镍的提取。为此,我们提出下列的流程,供实验研究工作中的参考。 The process of cobalt ore in some places cobalt oxide (CoO) of about 2 to 3%, containing titanium oxide (TiO_2) up to 2%, containing MrO_2 in more than 20%, other such as nickel and copper also contains a thousand points A few. We deal with this type of cobalt ores and should synthesize all these valuable metals as much as possible, especially with the exception of cobalt, with special emphasis on the extraction of titanium, manganese and nickel. To this end, we propose the following process for reference in experimental research.
